Application led october 8, i921. Serial No. menait.,

' to a route indicator adapted to be mounted upon the steering post ofan automobile, and operated loy a connection to the speedometer chain.llt is a further object to provide a device ot the character indicatedthat will le he simple, accurate and` positive in operation. andprovided with means tor rendering it inoperative and tor ed'ecting themanual adjustment of the indicator riloloon,

Figure l is. a sectional view on? line l-l or ligure 2., i

liligure 2 is a plan view or the device with the top removed and parthrolren away.l

Figure 3 is a sectional elevation showing the worm release construction.

Figure l is a diagrammatical view ot the device in position on thesteering post oit a vehicle. .l

ldigure` 5 is an enlarged detail section ot the speedometer chainconnection.

Referring more particularly to the draw ing, l show at l a casing ttedwith a cover 2 having awindow 3 therein, and with 'a ol amp d wherebylit is attached to the steering post of an automobile as indicated at 5.

i ltevoluloly mounted in casing l are spaced spools 6 and 7 arranged asshown. lnthe end of casing l opposite to spool 7 are-a pairo ofcontracting rollers 8 and 9 made oi snitahle material as vulcanizedrubber, the roller 9 being an idler and the roller 8 heing driventhrough the medium of a chart l0. Roller @carries a friction wheellik-contacting with a friction wheel 'l2 mounted to rear. Yvolve withspool 'At either end of window 5, and within the casing are mountedguides 13de, and at l5 is shown a rihloon of suitable material carryinga road map and mounted on spool e, 'lhis rihhon pase-es z over guidesIt-lll and under window 3,

move slowly under window 3.

thence between rollers 8-9 and on to spool 7., When shaft l0 is rotatedthe rihloon is drawn od of spool 6 loy rollers 8 and 9 and wound uponspool 7. Since spool 7 is driven by shaft l0 through the medium of`friction 55 wheels y11-12 it is wound up on spool l at a speedcommensurate with the speed ol shaft l0.

As a means for driving shaft l0 at a low speed proportional to the speedor? the co i vehicle, l mount .a shaft l@ in casing laat rightangles toshaft 1G and provide engaging worin gears l'? and 18 at the point oltheir intersection. @n shaft ll also provide another worm gear 19engaging a worm on gear 20 on a vertical. sha-tt 2l set in, casing l'and rotated hy a derihle drive 22 conn nected to the speedometer vchain23 of the automobile as at 23E. 'lhesaeeveral gears are so proportionedthat the riloloon, wim 7o Since its movements vary directly inproportion to the varying speed ot the vehicle, that portion or the maprepresenting the portion ot the road over which the vehicle is moving ia7a always in view.

The shaft 2l is separahle as atlt so that its upper portion 25 may heraised'and die engaged from the lower portion thereloy;V eo

rendering the device inoperative ln operation the spool ti is tted withrihhon carrying a road map between given points and the riloloonthreaded on the several elements as described. The device will nowautomatically display the map at e5 the proper speed as the roaddelineated thereon is traveled over. ln mamng a detour or during stopovers at intermediate places the connection 2d may he broken there-hypreventing thc unrolling ol the map. When the eo journey is again talrenup the inap may 'los adjusted -loy operating spools e and 7 Toy Y meansof buttons 26 or 27 as the case may he and the connection 2l againthrown into engagement., 1 n

llt may now loe seen that l have provided a device that is simple,compact, positive in operation and highly eilicient in its practik calapplication. c

llt is to he understood, ot course, that leo changes in form,construction and method one of saidspools to drive the same, a jour- 10of opera-tion may be made Within the scope nal bearing arm. extendingfrom the casing of the appended claim.
